Hello Anderson,
There are in principle two different ways to handle this requirement:
- Call a query (Pradeep Kumar N)
- Make sure that you call the "DataOnly" version because otherwise the BO buffer is replaced by the query result
- Of course use the "FromDb" version of the query
- Track by yourself (Ludger Bünger)
- Add transient fields for the relevant elements
- Copy the values in the "AfterLoading" event
- Compare the transient elements wioth the "real" ones in the "BeforeSave"
HTH,
Horst
